Bernardita’s program provides leadership in applied research, extension, and outreach for the PNW tree fruit industry. Her goal is improving orchard efficiency and fruit production through horticultural management practices and technology.
Main areas of interest are 1) Soils and plant nutrition; 2) Tree fruit stress management; and 3) General horticultural practices for tree fruit production.
